Early-blind human subjects localize sound sources better than sighted subjects
Article Abstract:
Three-dimensional spatial mapping, an ecologically critical function, has been studied in early-blind individuals with or without residual vision. Early-blind subjects were able to map the auditory environment the same as, or better than, sighed subjects, and they could correctly localize sounds monaurally. Blind individuals having residual peripheral vision were not as precise at localizing sounds as sighted or totally blind subjects.

Image statistics and the perception of surface qualities
Article Abstract:
The skewness of the luminance histogram and the skewness of sub-band filter outputs are correlated with surface gloss and inversely correlated with surface albedo and human observers use skewness in making judgments about surfaces. A visual after-effect based on skewness is observed, suggesting that there are neural mechanisms sensitive to skewed statistics and that their outputs can be used for estimating surface properties.

The blind leading the sighted: an eye-opening experience of the wonders of perception
Article Abstract:
The experiences of the people, who were blind since childhood and received their sight during their adulthood, help researchers in determining their perceptions, and in further studies related to the new vision and its development during the remaining period of their life. The advent of brain imaging technology helps in investigating the working of the brain after the acquisition of eyesight.
